Comparison Operators

We’ve seen == and < so far. Let’s document all six of the comparison operators we have at our disposal.

• ==
  equals

• !=
  not equals

• >
  greater than

• <
  less than

• >=
  greater than or equals

• <=
  less than or equals

Comparison operators can work on many different types. The exact rules are a bit beyond us right now, as they tie into traits, which we haven’t learned yet. For now, it’s enough to know that:

• Strings, numbers, Booleans, and units can all be compared with equals and not equals.

• Numbers can all be compared with the other four operators as well.

And we can see these in action using assert! together with assert_eq! and its not-equal counterpart assert_ne!:
